Chlorophyll is the pigment that gives plants and algae their green color. Plants use chlorophyll to trap light needed for photosynthesis . The basic structure of chlorophyll is a porphyrin ring similar to that of heme in hemoglobin, although the central atom in chlorophyll is magnesium instead of iron. The long hydrocarbon (phytol) tail attached to the porphyrin ring makes chlorophyll fat-soluble and insoluble in water. Chlorophyll a and chlorophyll b represent about 99% of the chlorophyll species found in edible plants (Figure 1; , while some algae and microalgae contain minor quantities of chlorophyll c pigments (e.g., Laminaria ochroleucaUndaria pinnatifida) . Chlorophyll a and b only have a small difference in one of the side chains but an intact phytol tail, while the common characteristic of chlorophyll c isoforms is the absence of a phytol tail. These structural differences cause each type of chlorophyll to absorb light at slightly different wavelengths.

Metallo-chlorophyll derivatives, including chlorophyllins, can be chemically synthesized or produced in industrial food processing; these compounds contain zinc, iron, or copper in place of the central magnesium atom . The most studied chlorophyllin, sodium copper chlorophyllin (SCC), is a semi-synthetic mixture of sodium copper salts derived from chlorophyll . SCC is often simply called ‘chlorophyllin’ in the older scientific literature, with newer publications specifying whether iron, zinc, copper, or magnesium chlorophyllin were studied. During its synthesis, the magnesium atom at the center of the ring is replaced with copper (or other metals), and the phytol tail is lost. Unlike natural chlorophyll, chlorophyllins (regardless of the metal used) are water-soluble. Although the content of different SCC mixtures may vary, two compounds commonly found in commercial SCC are trisodium copper chlorin e6 and disodium copper chlorin e4 .

Food addition
Research on bioactive substances in plant foods shows that the increasing consumption of fruits and vegetables is closely related to the decline of, etc. Chlorophyll is one of the natural biologically active substances. As a derivative of chlorophyll, metal tonic is the most unique of all natural pigments and has a wide range of uses.

For textiles
With the strengthening of people's awareness of environmental protection and the increasing attention to health, the negative effects of synthetic dyes used in textile dyeing on human health and the ecological environment have attracted more and more attention. The use of non-polluting green natural dyes to dye textiles has become the research direction of many scholars. There are few natural dyes that can dye green, and sodium copper chlorophyllin is a kind of food-grade green color pigment, which is a natural derivative of chlorophyll. It can be refined from the extracted chlorophyll through saponification, copper and other reactions. It is a kind of metal phylline with high stability, dark green powder, slightly metallic luster.

For cosmetics
It can be added to cosmetics as a dye. Sodium copper chlorophyllin is dark green powder, odorless or slightly odorous. The aqueous solution is transparent emerald green, which deepens with the increase of concentration. It is light resistant, heat resistant and stable. The pH of 1% solution is 9.5~10.2. When the pH is below 6.5, precipitation will occur in case of calcium. Slightly soluble in ethanol. Acid drinks are easy to precipitate. It has stronger light resistance than leaf green virus, and decomposes when heated to above 110 ℃.
